ABSTRACT

A rechargeable battery jump starting device having a highly conductive electrical pathway from a rechargeable battery of the device to a vehicle battery being jump started. The highly conductive pathway can be provided by a highly electrically conductive frame connecting one or more batteries of the rechargeable battery jump starting device to battery clamps of the rechargeable battery jump starting device.

FIELD

The present invention is directed to a portable rechargeable battery jump starting device configured for providing maximum conductivity and power delivery to a vehicle battery being jump started. The rechargeable battery jump starting device according to the present invention, for example, is useful for jump starting cars, trucks, heavy equipment, commercial vehicles, or equipment such as trucks, buses, commercial trucks, front loaders, dozers, back hoes, excavators, rollers, fork lift, specialized commercial equipment, logging equipment, airplanes, jets, and boats.

BACKGROUND

There exists U.S. Pat. No. 9,007,015 to Nook et al. entitled Portable Vehicle Battery Jump Start Apparatus with Safety Protection. This battery jump start apparatus utilizes a lithium ion battery pack. In this type of apparatus, there exists a need to maximize conductivity from the battery pack of the apparatus to the vehicle battery of the vehicle being jump started. For successful vehicle jump-starts, there are two main factors dictating the results. The first factor is the amount of power provided by the lithium ion battery pack, and the second factor is the maximum conductivity. You need both factors to have the best chance to jump-start big engines. One factor without the other factor is not enough.

Further, there exists PCT application no. PCT/US2016/024680 filed on 29 Mar. 2016 (published 17 Aug. 2017 as WO 2017/138963 A1) entitled Battery Assembly Device. The battery assembly device disclosed provides an enhanced electrically conductive battery assembly for use, for example, in a battery jump start apparatus.

In addition, there exists PCT application no. PCT/US2017/017289 filed on 10 Feb. 2017 (published 17 Aug. 2017 as publication no. WO 2017/139524 A1) entitled Battery Connector Device for a Battery Jump Starting Device. The battery assembly device disclosed provides an enhanced electrically conductive battery assembly for use, for example, in a battery jump start apparatus.

Also, currently there exist heavy duty battery jump starters using conventional lead acid batteries. The jump starters are heavy in weight (e.g. hundreds of pounds) and large dimensionally requiring the jump starter to be moved around using a fork lift. Thus, the current battery jump starters are not portable in any manner.

There exists a need for a portable improved battery jump starting device having significantly increased power output (i.e. high power output), reduced weight, and reduced size to replace conventional units.

This is especially true when making a compact and portable configuration of the battery jump starting device to allow minimizing size and distances between electrical components.

The left side of the battery jump starting device 10 is also fitted with a pair of light emitting diodes 28 (LEDS) for using the battery jump starting device 10 as a work light. For example, the LEDs 28 are dual 1100 Lumen high-intensity LED floodlights), as shown in FIGS. 1, 4, and 8. The LEDs 28 are configured to have seven (7) operational modes, including 100% intensity, 50% intensity, 10% intensity, SOS (emergency protocol), Blink, Strobe, and Off.

The battery jump starting device 10 is fitted with a heat sink 29 (FIG. 1) for dissipating heat from the LEDs 28. For example, the heat sink 29 is made of a heat conductive material (e.g. machined, molded, and/or die cast aluminum heat sink). The rib design shown (FIG. 1) facilitates the heat sink 29 transferring heat from the heat sink 29 to the surrounding atmosphere to prevent the LEDs 28 from overheating.

The battery jump starting device 10 is shown in FIG. 1 without battery cables. The battery jump starting device 10 is shown in FIG. 8 having cables 56, 58 respectively connected to battery clamps 60, 62 for connecting the battery jump starting device 10 to a battery to be jump started (e.g. vehicle battery). The battery jump starting device 10 can be configured to detachably connect to the set of battery cables 56, 58 respectively having the battery clamps 60, 62 (e.g. positive battery cable with a positive clamp, negative battery cable with a negative clamp). Alternatively, the battery jump starting device can be fitted with battery cables hard wired directly to the device and being non-detachable.

In the first embodiment shown in FIGS. 1 and 4, the left side of the battery jump starting device 10 is provided with POSITIVE (+) cam-lock 24 a and NEGATIVE (−) cam-lock 24 b. The cam-locks 24 a, 24 b include receptacles 25 a, 25 b (FIG. 4) configured for detachably connecting with connecting end 56 a (FIG. 11) of the positive battery cable 56 and the connecting end 58 a of negative battery cable 58, respectively. The cam-locks 24 a, 24 b are fitted with sealing caps 26 (FIG. 1) for closing and sealing the receptacles 25 a, 25 b of the cam-locks 24 a, 24 b, respectively, during non-use of the battery jump starting device 10.

The power circuit 30 of the battery jump starting device 10 is shown in FIG. 9.

The power circuit 30 comprises two (2) separate Lithium ion (Li-ion) batteries 32 (e.g. two (2) 12V Li-ion batteries) connected to the control switch 18 via a pair of cable sections 34, 36 (e.g. insulated copper cable sections), respectively. The control switch 18 is connected to the reverse currently diode array 48 (i.e. reverse flow protection device) via the cable section 44, and the control switch 18 is connected to the smart switch 50 (e.g. 500 A solenoid device) via cable section 40, as shown in FIG. 9.

The reverse current diode array 48 is connected to the one battery 32 via cable section 44, and the smart switch 50 is connected to the other battery 32 via cable section 46, as shown in FIG. 9.

The positive battery cable 56 having a positive battery clamp 60 is detachably connected to the positive cam-lock 25 a (FIG. 9), which is connected to the reverse current diode array 48 via cable section 52.

The negative battery cable 58 having a negative battery clamp 62 is detachably connected to the negative cam-lock 25 b (FIG. 9), which is connected to the smart switch 50 via cable section 54.

In the above described first embodiment of the power circuit 30, the electrical components of the power circuit 30 are connected together via cable sections (e.g. heavy gauge flexible insulated copper cable sections). The ends of cable sections are soldered and/or mechanically fastened to the respective electrical components to provide highly electrically conductive electrical connections between the electrical components.

In a modified first embodiment shown in FIG. 10, the battery cables 56, 58 are directly hard wired to the reverse current diode array 48 and smart switch 50, respectively, eliminating the cam-locks 25 a, 25 b, so that the battery cables 56, 58 are no longer detachable.

In a second embodiment of the power circuit to be described below, the cable sections 36, 40, 42, 44 located between the Li-ion batteries 32 and the reverse current diode array 48 and smart switch 50, respectively, are replaced with a highly electrically conductive frame (e.g. rigid frame).

The control switch 18 assembly is shown in FIGS. 12-15.

The control switch 18 comprises the following:

-   -   1) control knob 18 a;     -   2) front housing 72;     -   3) rear housing 74;     -   4) rotor 76 having a collar 76 a, legs 76 b, and legs 76 c;     -   5) springs 78;     -   6) pivoting contact 80 each having two (2) points of contact         (e.g. slots 80 c);     -   7) separate terminals 82, 84, 86, 88;     -   8) connected terminals 90, 92;     -   9) conductive bar 94     -   10) O-ring 96;     -   11) O-ring 98; and     -   12) O-ring 100.

The control knob 18 a comprises rear extension portions 18 b, 18 c. The extension portion 18 c has a T-shaped cross section to connect into a T-shaped recess 76 e (FIG. 12) in rotor 76 when assembled. The rotor 76 is provided with a flange 76 a configured to accommodate the rear extension portion 18 b (e.g. round cross-section) therein.

The pair of legs 76 c (e.g. U-shaped legs) of the rotor 76 partially accommodate the springs 78, respectively, and the springs 78 apply force against the pivoting contacts 80 to maintain same is highly conductive contact with the selected contacts 82 b-92 c of the terminals 82-92.

The pivoting contacts 80 each have a pivoting contact plate 80 a having a centered slot 80 b configured to accommodate an end of each leg 76 b of the rotor 76. When the rotor 76 is turned, each leg 76 b actuates and pivots each pivoting contact plate 80 a.

Further, the pivoting contact plates 80 a each having a pair of spaced apart through holes 80 c (e.g. oval-shaped through holes) serving as two (s) points of contact with selected contacts 82 c-92 c of the terminals 82-92.

The terminals 82-92 have threaded posts 82 a-92 a, spacer plates 82 b-92 b, and conductive bar 94, respectively, configured so that the contacts 82 c-92 c are all located in the same plane (i.e. plane transverse to longitudinal axis of the control switch 18) to allow selective pivoting movement of the pivoting contacts 80. The threaded posts 82 a-92 a of the terminals 82-92 are inserted through the through holes 74 a, respectively, of the rear housing 74.

The O-rings 96, 98, 100, as shown in FIG. 12, seal the separate the various components of the control switch 18 as shown. After assembly of the control switch 18, a set of screws 75 connect with anchors 74 b of the rear housing 74 to secure the front housing 72 to the rear housing 74 as shown in FIG. 12.

The control switch 18 is a 12V/24V selective type switch as shown in FIG. 13. The configuration of the pivoting contacts 80 in the first position or Position 1 (i.e. Parallel position) is shown on the left side of FIG. 13, and the second position or Position 2 (i.e. Series position) is shown on the right side of FIG. 13.

The rear side of the control switch 18 is shown in FIG. 14. Another highly electrically conductive bar 94 is provided on the rear outer surface of the rear housing 74. The fully assembled control switch 18 is shown in FIG. 15.

The second embodiment of the battery jump starting device 110 is shown in FIGS. 20-25 with the cover 112 removed. The cover for the battery jump starting device 110 is the same as the cover 12 of the battery jump starting device 10 shown in FIG. 1-8.

In the second embodiment of the battery jump starting device 110 compared to the battery jump starting device 10 shown in FIGS. 1-8, the cable sections 34, 36, 40, 42, 44, 46 (FIG. 9) in the first embodiment are replaced with a highly electrically conductive frame 170.

The battery jump starting device 110 comprises a pair of 12V Li-ion batteries 132 directly connected to the highly electrically conductive rigid frame 170. Specifically, the tabs (not shown) of the Li-ion batteries are soldered to the highly conductive rigid frame 170.

The highly electrically conductive rigid frame 170 is constructed of multiple highly electrically conductive conductors or frame members 134, 136, 140, 142, 144, 146, 152, 154 connected together, for example, by mechanical fasteners (e.g. copper or aluminum nut and bolt fasteners) and/or soldering. For example, the highly electrically conductive rigid frame members are made of highly electrically conductive copper rods. Alternatively, the highly electrically conductive copper rods can be replaced with highly electrically conductive copper or aluminum plates, bars, tubing, cables, or other suitably configured highly electrically conductive material (e.g. copper stock material of a various cross-sectional shapes, sizes, or gauges). The highly electrically conductive rigid frame 170 comprises highly electrically conductive conductors or frame members 134, 136, 140, 142, 144, 146, which can be insulated (e.g. wrapped, insulated, heat shrink cover) in at least key areas to prevent any internal short circuiting.

The highly electrically conductive rigid frame members can be configured with flattened end portions (e.g. flattened by pressing) each having a through hole to provide part of a mechanical connection for connecting successive or adjacent highly electrically conductive conductors or frame members and/or electrical components together using a highly electrically conductive nut and bolt fastener (e.g. copper or aluminum bolt and nut). In addition, the highly conductive rigid frame member can be formed into a base (e.g. plate or bar portion) for supporting or connecting with an electrical component.

For example, the reverse flow diode assembly 148 has three (3) base portions, including (1) an upper highly electrically conductive rigid bar 148 a (FIG. 16) having a flattened end portion 148 aa connected to the flattened end portion 144 a of highly electrically conductive rigid frame member 144 using a highly electrically conductive fastener 206 (e.g. made of copper or aluminum) having a highly electrically conductive bolt 206 a and highly electrically conductive nut 206 b; (2) a lower highly electrically conductive rigid bar 148 b made from a flattened end portion of highly electrically conductive rigid frame member 144; and (3) a center highly electrically conductive rigid bar 148 c made from a flattened end portion of the highly conductive rigid frame member 152.

As another example, the smart switch 150 (FIG. 16) comprises a highly electrically conductive rigid plate 150 a serving as a base supporting the solenoid 150 b. The highly conductive rigid plate 150 a is provided with through holes for connecting the highly electrically conductive rigid frame members to the smart switch 150 (e.g. highly electrically conductive rigid frame member 142) using highly electrically conductive fasteners 206.

The stock material (e.g. copper or aluminum plate, bar, rod, or tubing) selected for construction of the highly electrically conductive rigid frame 170 has substantial gauge to provide high electrically conductivity and substantial rigidity. The “rigid” nature of the highly conductive rigid frame 170 provides the advantage that the highly conductive rigid frame remains structurally stiff and stable during storage and use of the battery jump starting device 110.

For example, the highly conductive rigid frame 170 is designed and constructed to significantly prevent flexing, movement, bending and/or displacement during storage or use so as to prevent electrical shortages of the highly electrically conductive rigid frame touching other internal electrical components or parts of the electronic assembly. This “rigid” nature is important due to the high electrically conductivity path or pathway of electrical power flowing from the Li-ion batteries through the power circuit and reaching the battery clamps 60, 62. It is a desired goal and feature of the present invention to electrically conduct as much power as possible from the Li-ion batteries to the battery being jump started by the battery jump starting device by reducing or minimizing any electrical resistance by using the heavy duty and highly electrically conductive frame 170 arrangement disclosed.

As an alternative, the highly electrically conductive rigid frame 170 can be constructed as a single piece having no mechanically fastened joints (e.g. one piece construction, soldered pieces). For example, the highly electrically conductive frame can be made from a single piece of stock material and then formed into the highly conductive rigid frame. For example, a billet of highly conductive copper can be machined (e.g. milled, lathed, drilled, bent, formed) into the highly electrically conductive rigid frame. As another example, a copper or aluminum sheet or plate can be bent and/or machined into the highly electrically conductive rigid frame 170. As a further alternative, the highly electrically conductive frame 170 can be metal molded (e.g. loss wax process).

As another alternative, the highly electrically conductive rigid frame 170 is made of multiple highly electrically conductive frame members connected together into a unitary structure. For example, the highly electrically conductive rigid frame is made of highly electrically conductive sections of stock material (e.g. copper rod, plate, bar, tubing), which are bent and soldered and/or welded together.

The battery jump starting device 110 further comprises a resistor array 202 (e.g. 12 V 5 A XGC) comprising a printed circuit board (PCB) 202 a serving as a base supporting an array of individual resistors 202 b, as shown in FIGS. 17 and 19. The PCB 202 a also supports the dual 2.1 amp (A) USB OUT ports 120 c, 120 d, the 18 A 12V XGC OUT port 20 e, and the 5 A 12V XGC IN port 20 e.

The highly electrically conductive frame 170 can comprise the highly electrically conductive conductors or frame members 134, 136, 140, 142, 144, 146 and one or more electrical components (e.g. control switch, smart switch, plate 150 a, reverse flow diode assembly 148) together forming and defining the of the high electrically conductive frame 170.

The highly electrically conductive frame member 170 can at least partially enclose or fully enclosed the batteries 132 in one or more planes of the battery (e.g. plane located perpendicular to x, y, z axes of the batteries 132). Further, the highly electrically conductive frame member 170 are located adjacent to and close to the outer surfaces of the batteries 132 to provide a compact configuration while preventing electrical shorts with electrical components of the rechargeable jump starting device 10.

The left side of the battery jump starting device 110 is also fitted with a pair of light emitting diodes 128 (LEDS) for using the battery jump starting device 110 as a work light. For example, the LEDs 128 are dual 1100 Lumen high-intensity LED floodlights), as shown in FIG. 16. The LEDs 128 are configured to have seven (7) operational modes, including 100% intensity, 50% intensity, 10% intensity, SOS (emergency protocol), Blink, Strobe, and Off.

The battery jump starting device 110 is fitted with a heat sink 129 (FIG. 16) for dissipating heat from the LEDs 128. For example, the heat sink 129 is made of a heat conductive material (e.g. molded or die cast metal plate). The heat sink 129 is provided with ribs 129 a transferring heat to the surrounding atmosphere to prevent the LEDs 128 from overheating.

The battery jump starting device 110 is shown in FIG. 16 without any battery cables having battery clamps for connecting the battery jump starting device 110 to a battery of a vehicle to be jump started.
